Orange Light:

Safety, Design and Environmental Protection

Make the most of amber-colored LED light in Urban Lighting

For a long time orange-colored light was used in urban lighting in the form of high/low pressure sodium vapor lamps.

With the modernization to LED technology and the ban on most conventional ballasts valid since this year, this light color has almost completely disappeared from the product catalogue of most manufacturers. The OSRAM company Siteco is now adding orange-colored light to a part of its LED outdoor luminaire portfolio because this offers significant advantages in certain areas compared to the familiar white light of LED technology.

That's why it makes sense to use it in the following areas:

1) Illumination of conflict areas:

Conflict areas are e.g. crossings, crosswalks or crossing aids for pedestrians.
Ensures safety - as traffic’s attention is brought to the conflict zone? The increased attention decreases the probability of an accident

2) Design with light:

The selected light color influences the appearance of the illuminated material. Thus the appearance of the material can be influenced positively or negatively.?Amber colored light is ideally suited for illuminating buildings with a brick or sandstone facade because the warm light color emphasizes the warm fundamental tone of the facade. It is less suitable for concrete, glass or limestone facades.

3) Modernization of lighting systems:

Because of the conversion to LED, a different light image is created. In rare cases residents are feeling disturbed by the new lighting installation. Municipalities that want to have a similar light image can use LED lamps with amber-colored light as it works a good alternative to the sodium-vapor high/low-pressure lamps.

4) Reduction of light pollution

In clear air, short-wave blue light is diffused much further than long-wave red light. That is why the daytime sky appears blue.
That means: The higher the blue light content of the light source, the higher is the scatter in all directions > higher light pollution.

5) Protect the environment:

LEDs are free of IR and UV radiation. This makes them very "insect-friendly" and therefore environmentally friendly. Also the light color plays a role. Insects are less attracted to the yellowish light of a sodium vapor high/low-pressure lamp than the white light of a high-pressure mercury lamp.?Even when looking at the LED, the 3000K variant attracts far less insects than the version with 6000K. An even warmer light color of the LED promises further improvement.
In areas which are particularly vulnerable, such as in natural or national parks or near waterways (cannels with ship locks), the use can be useful.
